background: intracerebral  hemorrhage (ich) is the  most fatal subtype  of stroke.  despite  limited effective therapy, there  is no  accepted clinical grading  scale to  predict  in- hospital  mortality,  especially  in developing  nations.  the purpose  of this study was to assess the  predictors  of in- hospital mortality among a sample of iranian patients  with spontaneous ich for use at th...

to determine the factors affecting the outcome of patients with traumatic acute subdural hematoma, we reviewed the records of7 4 consecutive comatose patients with a glascow coma scale score (gcs) of less than 8 who had been admitted to imam hosein medical center from 1990 to 1996 and had undergone a uniform treatment protocol. the overall mortality rate was 73% and 23% had functional recovery,...

BACKGROUND selecting the correct statistical test and data mining method depends highly on the measurement scale of data, type of variables, and purpose of the analysis. Different measurement scales are studied in details and statistical comparison, modeling, and data mining methods are studied based upon using several medical examples. We have presented two ordinal-variables clustering example...

We propose the use of the preconditioned interval Gauss-Seidel method as the backbone of an eecient linear equality solver in a CLP(Interval) language. The method, as originally designed, works only on linear systems with square coeecient matrices. Even imposing such a restriction, a naive incorporation of the traditional precon-ditioning algorithm in a CLP language incurs a high worst-case tim...

INTRODUCTION Despite the strong evidence of the clinical utility of QTc prolongation as a surrogate marker of cardiac risk, QTc measurement is not part of clinical routine either in hospital or in physician offices. We evaluated a novel device ("the QT scale") to measure heart rate (HR) and QTc interval. METHOD The QT scale is a weight scale embedding an ECG acquisition system with four limb ...
